You know I've got an old keg that's got a leak up on the neck near one of the ball lock posts I use it all the time Valka.
On brew day I send my first run of hot chill water into it to store for cleaning.
If I've got extra sanitizer in there it goes.
Cleaning liquid in it goes.
I rekon a brew can't have enough buckets laying around and a stainless one is extra special.
